Condition(s) targeted: Ischemic Stroke

Intervention: Cilostazol (Drug); placebo (Other)

Phase: Phase 4

Status: Completed

Sponsored by: China Medical University Hospital

Official(s) and/or principal investigator(s):
Chung Y. Hsu, MD. Ph.D., Principal Investigator, Affiliation: China Medical University Hospital


The purpose of this study is to investigate the Safety and Efficacy of Cilostazol in slowing down the progression of peripheral arterial disease (PAD) in ischemic stroke patients with PAD in Taiwan.

Clinical Details

Official title: The Safety and Efficacy of Cilostazol in Ischemic Stroke Patients With Peripheral Arterial Disease (SPAD Study)

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Primary outcome: The primary endpoint for this study is slowdown of PAD progression based on ABI.

Secondary outcome: Carotid intima-media thickness

Detailed description: One thousand patients will be randomized to take cilostazol (500 patients) or placebo (500 patients) in parallel groups. Patients will be screened and evaluated on Visits 1 to assess their eligibility prior to randomization. The treatment period (Visit 1-6) will last 12 months and the patient will receive initial and follow-up evaluation (section 4. 5) including history and physical examinations, and baseline and end of treatment ABI and carotid IMT assessments. Vascular events and death as well as adverse events including bleeding complications will also be recorded at intervals as detailed in section 4. 5.


Minimum age: 50 Years. Maximum age: N/A. Gender(s): Both.
